Let's say I've done the following in PHP:
$image = imagecreatefromjpeg('myImage.jpg);
Is there a way the image data from $image could be converted to a string that could be sent in my AJAX response?

What do you want to do with the response? Do you want to display the image? Have the user download it? Based on what your final goal is, there could be a different solution.gen_Eric– gen_Eric2013-09-18 17:51:30 +00:00Commented Sep 18, 2013 at 17:51

move it to a folder and then send the path to it as a string in the ajax.nathan hayfield– nathan hayfield2013-09-18 17:51:31 +00:00Commented Sep 18, 2013 at 17:51

1@nathanhayfield I'd considered just sending a path instead... K.I.S.S.Benjamin Allison– Benjamin Allison2013-09-18 17:52:55 +00:00Commented Sep 18, 2013 at 17:52

Something like this should work to get a base64-encoded string from the image:
<?php
$image = imagecreatefromjpeg('myImage.jpg');
ob_start();
imagejpeg($image);
$imagestring = ob_get_contents();
ob_end_clean();
$encoded = base64_encode($imagestring);
?>
<pre><?php echo $encoded ?></pre>
<img src="data://image/jpeg;base64,<?php echo $encoded ?>" alt="myImage" />
This will output the base64-encoded image as a string and will also display the image using that encoded string.

Use base64, or some other binary->text encoding schemes available, and pass it with the data in ajax, and decode at the client.
PHP has base64 functions, see http://php.net/manual/en/function.base64-encode.php
